@Wwi Patented Aug. 16, v1910. y Y z SHEETS-SHEET 2.

i are temporaril The back piece is of substantially twice the length of the leaves -5- which are attached thereto, one in advance of the other in 4close juxtaposition near one end until substantially half of the back piece is filled with leaves leaving the other half unprovided with leaves so that the entire series of such leaves may be folded backwardly or downwardly upon themselves within the area of the back piece. s y

A leaf rest `i-lis detachably secured to the end of the .back piece to which the leaves are applied and is disposed in'an inclined position or at an obtuse angle with the back piece to form a rest for supporting the leaves in an inclined position relatively to the back piece; This rest -15- preferably consists of a U-shaped piece of wire havin its ends detaehably interloclred or slidab y engaged in suitable loops -16- which are cut' and stamped from the main body of the back piece -11- and are similar to the loops -l2-'.

The clasps -7- are preferably attached to the leaves -5- in pairs, one pair near the inner end of base and another pair near the outer end, each clasp preferably consisting of a U-shape metal clasp passed through an apcrturein the leaf and having its opposite arms movable toward and from and preferably spring-tensioned toward oppo,

site faces of said leaves so as to effectively retain one or more loose sheets which may be inserted between said arms and the adjacent faces of the leaf. l

`When this device is used as a telephone index or for similar purposes, the loose sheets are preferably made in book form or folded substantially midway between -their ends either by attaching two sheets together or creasing a single sheet, cach sheet being provided with a slit or slot at its fold for ,receiving corresponding arms of the clasps -7- thus permitting the sheets to .be readily attached or detached from their supportingleaves -5.

The outer end edges of the sheet timay be further retained by passing it' under the corresponding arm of the outer clasp -7- as clearly shown in Fig. 6. It is now clear that one-half of each sheet is held in place by the inner and outer clasps and the other half of the sheet is free to be'folded backward and forward thus permitting both sides of the movable half and the exposed side of the other half to be used for the reference names of other items.A It is also clear upon reference to Fig. 6 that by passin the clasps -7- through the leaves -5-'- Ieaving their opposite arms at opposite sides of said leaf, the .loose sheets may be fastened to both sidesof each leaf and both sheets of each leaf are, therefore, readily available for the reception of reference names or other items making a very compact reference tilewhich is particularly adapted for telephone use but may be used with equal advantage in other relations as a ready reference file. v y

In Fig. 8 I have shown one of the leaves -6- as provided at the fold with apertures *Gefor receiving corresponding arms of the inner clasps -7-.

In Fig. 9 I have shown two separate sheets as fastened together by iiexible hinges leaving the central portion open to forni a lengthwise slit -6- which also receives the corresponding arms of the inner clasps -7-. n

The pocket members -4- have their opposite edges inserted in the grooves 1% and are held in place by the fian yes -13- and are preferabl made of car board or similar material w ich is sti yet suliiciently yielding to permit its central portionto be sprung outwardly away from the back piece -3- to receive a portion' of a ad ,-a,, the pad in lthis instance providldd with a tongue awhich is slipped over one of the edges of and between the pocket member 4- and back -3- to temporarily hold the pad upon the pack piece.

In practice the bases 8- of the leaves 5- are adhesively or otherwise secured to the plate llthe latter being slidable lengthwise of the back piece -11- and being heldagainst lateral displacement by the ianges -13-. This permits the plate -4 withl the several leaves 5 thereon to be removed by simply withdrawing suoli plate from one end of the back ieee --11-. It'is evident, however, that in either case the leaves -5- are removable from the,back piece ll-.

The operation of my invention will now be readily understood upon reference to the foregoing description and accompanying drawing.

What I claim is:

1. In a reference file, a back piece, index leaves hinged to the back piece, clasps on the index leaves, and loose leaves havin portions thereof fastened by the clas an other portions free to turn backwar and forward.

2. In a reference file, a back piece, an inoomeee (len leal hinged to the beek i ille leoni9 and n loose leol lo Cledu omini/self end provided with e slit al; the fol through which s portion of the elesp is inserted to xelein the loose leaf on the lndex leaf.
